Dreeam 9a4efaa230 Drop patch that causes performance regression
Originally vanilla logic is to use stream, and Mojang switched it to Guava's Collections2
since 1.21.4. It is much faster than using stream or manually adding to a new ArrayList.
Manually adding to a new ArrayList requires allocating a new object array. However, the Collections2
lazy handles filter condition on iteration, so much better.
